Gelion to deliver 100 MWh of zinc-bromide battery storage for Papua New Guinea project
Gelion, an Australian zinc-bromide battery tech specialist, has agreed to deliver 100 MWh of energy storage to Mayur Renewables for clean energy projects in Papua New Guinea under a new deal.
Energy efficiency a good substitute for long-term storage, says NREL
A 60% reduction in building energy use will be key to achieving a low-cost, 100% renewable energy grid, according to a new study by the U.S. National Renewable Energy Laboratory.
Isomer passivation for a 21.4% efficient perovskite module
An international team of scientists trialled a new approach to passivating defects in perovskite solar cells. Using a tailored arrangement of atoms, the team was able to overcome challenges related to the formation of a two-dimensional perovskite layer on top of the active cell material, and reach 21.4% conversion efficiency for a 26cm² active area, which they claim as a record for a perovskite device of this size.
The Hydrogen Stream: Three more ports want to become hydrogen hubs
Antwerp, and Zeebrugge, in Belgium, and Newcastle in Australia all want to speed up green hydrogen development.
Gallium arsenide nanowire solar cell with 7.7% efficiency
Norwegian scientists have developed a gallium arsenide (GaAs) nanowire solar cell that can be used as a top cell in a dual tandem cell with a bottom silicon cell. The device is claimed to be the most efficient single-junction GaAs nanowire solar cell grown on a silicon substrate so far.
New laser-cutting system for half-cut, shingled PV cells
German manufacturer 3-D Micromac said it has developed a new machine that can produce more than 6,000 wafers per hour. It is suitable for solar cells with temperature-sensitive coatings, or depositions such as heterojunction devices.
Quantum dot solar window with 3.6% efficiency
U.S. manufacturer UbiQD has developed a solar window with laminated glass and luminescent solar concentrators, based on copper indium sulfide and zinc sulfide quantum dots. It is now testing pilot installations in Nevada.
Floating PV tested at water treatment plant in South Africa
The pilot system was built with the Hydrelio floating platforms developed by French specialist Ciel&Terre. The project performance will be evaluated during a full seasonal weather cycle.
The world’s largest seawater heat pump based on CO2 as refrigerant
Swiss-headquartered technology corporation ABB is supplying integrated electrical infrastructure for the construction of a 50 MW seawater heat pump in Denmark. The heat pump technology will be provided by German specialist MAN Energy Solutions.
End-of-life management of solar PV waste in India
A new study proposes an ‘extended producer responsibility’ regulatory framework for end-of-life solar PV management in India.
